Weiyang Palace Ruins (Han Chang'an)

When the Han dynasty built Chang'an as capital of empire (2nd century BC), its palace was Weiyang — among the largest palace complexes on ancient Earth, the seat from which Emperor Wu ran the Silk Road's opening act. What remains is archaeology, not architecture: massive rammed-earth platforms rising out of an enormous grass park, the outlines of halls you reconstruct in your head.

That emptiness is the point. Stand on the central axis at dusk with wind in the grass and almost nobody around, and the 'ancient capital' phrase stops being a slogan.

Enter free, no ticket, grounds open around the clock (per current reporting). One to two unhurried hours covers the core: the front-hall platform, the central-axis sightline, the edge where the city wall trace runs. There's little signage in English and little shade — water, hat, and comfortable shoes.

It pairs naturally with Silk Road reading: our silk-road story explains why this particular empire's ruins matter. Combine with a morning at Daming Palace (the Tang sequel, east side) for the full capitals-in-one-day double.

It sits in the city's northwest, well outside the Ming wall. Metro Line 1 to Zaohe station then a 15-minute walk or short ride; a taxi from the Bell Tower runs ¥35–50, 25–35 minutes. Nothing touristy sits nearby — go fed, or make it a picnic.

Honest verdict: if your time is short, the Terracotta Army and the wall outrank it. But for a second visit, a history reader, or anyone who felt Xi'an's core was too polished — this is the city with its makeup off.
